Documentation notice: This technical documentation was independently rewritten from an archived supplier source. Check technical details and commands against the product version and manufacturer documentation before use.

Summary

The Waveshare SX1302 LoRaWAN Gateway HAT connects a Raspberry Pi via the 40-pin GPIO header to a Mini-PCIe socket for the LoRa gateway module. It supports EU868 (863–870 MHz), offers +26 dBm transmit power and -141 dBm receive sensitivity at 125 kHz/SF12, and includes an optional GNSS module (GPS L1/BD B1) for time-stamping and positioning.

Technical overview

• Base module: Semtech SX1302/3 baseband chip with integrated PA/LNA; +26 dBm transmit power, -141 dBm receive sensitivity @125 kHz/SF12.
• Interfaces: SPI, I2C, UART; external 52-pin Mini-PCIe connector for integrating the module into embedded systems.
• GNSS option: GPS L1 (1575.42 MHz) and BD2 B1 (1561.098 MHz); positioning accuracy <2.5 m CEP; provides accurate clock and location info for the gateway.
• Operating temperature range: -40 °C to +85 °C; module dimensions: 50.95 mm × 30 mm.
• LoRaWAN protocol: Class A/B/C nodes, OTAA join flow using AppEUI/DevEUI/AppKey; regional frequency bands such as EU868 must be respected.
• Demo environment: The wiki demo is based on The Things Stack (TTS) and the official Semtech SX1302 library; for self-hosted cloud servers, lorawan-stack or ChirpStack can be used.
• Raspberry Pi 4B: Demo is primarily designed for Pi 4B; when using Pi 5, the GPIO pins need to be adjusted.
• Hardware connection: HAT plugs onto the 40-pin GPIO header; place the GPS antenna with the unlabeled side facing up in open sky area.
• Power consumption: Transmit 710 mA @5 V (GPS on), Receive 99 mA @5 V (GPS on), Sleep 41 mA @5 V (GPS off).

Commands and examples – verify before use: 

enable_uart=1
#dtoverlay=pi3-miniuart-bt (auskommentieren bei Pi 3B)
sudo reboot

Notes and version constraints

• The wiki demo is validated only for Raspberry Pi 4B; for Pi 5 the GPIO pin assignments must be manually adjusted – verify before deployment.
• SPI errors at gateway startup are often caused by SPI not being enabled or poor contact at the Mini-PCIe gold fingers; enable SPI and press the module firmly.
• The demo uses The Things Stack (TTS); when using other network services (e.g., ChirpStack, lorawan-stack), configuration steps must be verified separately.
• Regional frequency parameters (EU868 vs. other bands) must comply with local radio regulations – confirm before commissioning.
• Version-specific steps (e.g., drivers, libraries) may differ across OS versions; verify current compatibility manually.
